Several MCM and MCM50K deadlines are quickly approaching!

Good news, more entries have become available for the Marine Corps Marathon (MCM), but you have to act fast. Registration for the live and virtual MCM and the MCM50K will officially close on September 7.

Register Now!


This date also marks the closing of the transfer program for both the marathon and the ultra. After September 7, participants will no longer be able to transfer their bib to another runner or switch from the live category to the virtual option. Additionally, runners will no longer be able to switch from the MCM to the MCM50K or vice versa. Illegal documented transfers will result in a disqualification.

If you can’t make it to the expo for packet pick up on October 28 & 29 and do not have a proxy to pick up for you, please sign up for bib mail out. There is no bib issue on event day. You can purchase the bib mail out option by logging into your registration account. Bib mail out for all MCM Weekend events will also close on September 7.

The last date to defer for the MCM & MCM50K to 2023 will be September 25. Deferments are only allowed for the live MCM and MCM50K.

Registration and transfers for the MCM10K will remain open.
